Description:
The Aberdeen-Springfield Canal, a large open channel irrigation system in southeastern Idaho, is experiencing fluctuating flow rates and water levels due to the non-continuous operation of some pumped turnouts. The fluctuations cause problems in system management and flow variations at other turnouts which require a constant water level to receive a steady flow of water. The canal system was simulated using the hydraulic simulation model CANAL, developed at Utah State University. The objectives were to determine the effects of the non-continuous turnout operation and to evaluate the effects of alterations to the canal system upon fluctuating flow rates and water levels. Simulations evaluated increasing the number and size of spillways, modifications to channel cross sections, modification and addition of check structures, and restricting the timing and number of turnouts with non-continuous flow. Non continuous turnout operation was found to cause little variation in water level in some areas of the canal system, and large variation in others. This fluctuation was largely dependent upon the volume of flow, canal cross section, and the presence (or absence) of spillways. Feasible alterations to the canal system had limited effects upon the fluctuations in flow rate and water levels caused by the non-continuous turnout operation. Limiting the number of turnouts operation non-continuously and the length of time for which the turnouts operated non-continuously was effective in controlling the resulting fluctuations. Submitted to the Aberdeen-Springfield Canal Company, Aberdeen, Idaho.
